[PATCH 1/1] MTD: Fix MTD_MODE_RAW write fail

[Frank Li]

mtdchar have not initilized all field of struct mtd_oob_ops
in mtd_write when mode is MTD_MODE_RAW.

function nand_do_write_ops
	if (ops->ooboffs && (ops->ooboffs + ops->ooblen > oobmaxlen))
		return -EINVAL;

ooboffs is not initilized at mtd_write.
So random data cause nand_do_write_ops return fail.
